This invention relates to an inlet manifold for internal combustionengines, the general object of the invention being to provide themanifold throughout its length with internal baffles which are soarranged that there is no direct passage for the combustible mixture sothat the fuel is thoroughly broken up and mixed with the air and thus amixture will be delivered to the cylinders which will cause the engineto operate at its maximum elliciency. p

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several Views, and in which Figure 1is a view of a manifold constructed in accordance with this invention,parts being in section.

Figure 2 is an enlarged sectional View through a portion of themanifold.

Figure 3 is a section on line 33 of Figure 2. v r

Figure 6 is a section on line 66 of Fig ure 2.

As shown in these views, the manifold 1 is formed with internal bafiiesor fins 2 which are cast integral with the manifold and these bafflesextend inwardly from the walls of the manifold. These bafiles arepreferably ar ranged in pairs, as shown in the drawings, with themembers of each pair being connected with opposite sides of themanifold, with their free ends overlapping and with the members of eachpair spaced apart.

angular space between two baffles, it will" strike another baffle sothat the mixture is prevented from passing through the manifold in astraight path or a spiral one, and

thus it will be broken up into a number of streams which will comingleand this action will continue from the time the mixture enters themanifold until it passes from the manifold. Thus the mixture of fluidand air will be thoroughly combined, and the particles of fluid will bebroken up into minute parts. By having the baffles arranged on theentire length of the manifold, possibilities of the fluid separatingfrom the air isavoided, which will take place if the baffles 'pflipldnotextend the full length of the mani- From the foregoing it will be seenthat the mixture is thoroughly broken up" and held in suspension untilit passes into the cylinders, where it is ignited, so that thecombustibility of the mixture is greatly increased. With this invention,a saving of fuel is secured, due to the perfect mixture of the fuel andair and this invention renders the use of a heating device unnecessary,

though, of course, one may be used, if desired. I

It is thought from the foregoing 'descrip-' tion that the advantages andnovel features of my invention will be readily apparent. I desire it'tobe understood that I may make changes in the construction and in thecombination and arrangement of the several parts, provided that suchchangesfall within the scope of the appended claim.

What I claim is l A manifold of theclass described having baffles formedintegral with its internal walls, the baliles being arranged inlongitudinally extending rows extending from one end of the device tothe other, With each row diametrically opposite another row, with thebaflles of each pair of rows arranged impairs, the baffles of each pairbeing slightly spaced apart, with their inner'ends overlapping,alternate rows of baflles being arranged a quarterrturn from each otherand all the bafiies being of rectangular shape with the baffles inalternate rows extending across the space 10 between the battles of theother alternate rows whereby the fluid passing through the 7 device isprevented from following astraight path or a spiral one. r v

In testimony whereof I aflix my signature.
